SIGMUND V. HUBER, OF PITTSBURG, PENNSYLVANIA.

ROLLING-MILL.

$PEGIFICATION forming part of Letters Patent N 0. 671,439. dated April 9, 1901.

Application filed June 18, 1900. Serial No. 20,665- (No model.)

To all whom it may concern:

Be it known that I, SIGMUND V. HUBER, a

ism for rolls both of the two-high and the.

a and engaginga threaded opening in the block three-high type.

The invention has for its object a construction or arrangement of mechanism whereby both ends of a roll may be simultaneously adjusted and also whereby one end of the roll may be adjusted so as to produce equal reduction or any desired difference of reduction on the edges of the article to be rolled.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a top plan view of a mill having my improvement applied thereto. Fig. 2 is a side elevation of the upper portion of the mill and theadjusting mechanism of the top roll. Fig. 3 is a view similar to Fig. 1 on an enlarged scale. Fig. 4 is a sectional view, the plane of section being indicated by the line IV IV, Fig. Fig. 5 is a sectional view on the plane indicated by the line V V, Fig. 3; and Fig. 6 is a View similar to Fig. 3, illustrating a modification of the construction shown in the latter figure.

In the practice of my invention the housings 1 are constructed in the usual or any suitable manner and the rolls mounted therein, as is customary. Suitable adjustingscrews 2 are provided for adjusting the upper roll. On the upper end of these screws are secured wheels 3, provided on the upper surface of their perimeter with a series of teeth which are adapted to be engaged by portions of levers 4 and 5, which have their inner ends pi-votally connected to yokes 6, loosely mounted on the upper ends of the adj usting-screws. These levers 4 and 5 are connectedtogether by means of a strap formed in two sections 7 and 7*, connected together by a turnbuckle 8, whereby the straps may be lengthened or shortened, as required, for purposes of adjustment, ashereinafter described The sec formed in the other part.

tion 7 is pivotally connected to the lever 4, as clearly shown in Figs. 1, 3, and 6. In my preferred construction the section 7 is provided with a slot 9, in which is mounted a block 10. This block is adapted to be detachably connected to the lever 5 by a pin 11 on one of said parts projecting through an opening The block is adapted to be adjusted back and'forth in the slot in the section '7 by means of a screw 12, passing loosely through the end wall of the slot 10. The screw is held from longitudinal movement through the end wall of the slot by a hand-wheel 13 on the other end of the screw and a collar 14, secured to the screw inside the wall of the slot, as shown in Figs. 3 and 4.

When it is desired to adjust the upper roll, the levers 4 and 5 are raised up out of engagement with the crown-toothed wheels 3 and 3 and then shifted to the right or left, according to the adjustment required, and lowered to take newengagement with the said wheels. Thelevers are then shifted to the left or right, and this operation is repeated until the roll has been properly adjusted. As the levers are tied together, so as to move equally and simultaneously in the operation described, and as the teeth on the wheels 3 3 are spaced equally, both ends of the roll will be raised or lowered an equal amount.

If it is foundthat one end of the roll effects a little greater reduction than the other end, the hand-wheel 13 is operated, thereby shifting the lever 4, the block 10 and the lever 5 having been previously locked as against movement. The block 10 being held stationary, it is evident that the rotation of the screw 12 will shift the connection 7 and 7, and with it the lever 4, and thereby raising and lowering the end of the roll with which the screw operated by the lever 4 is in engagement.

The means for locking and holding screws in their adjusted position consists of a plate 15,secured upon one of the housings and provided with a series of holes a, a p'late 16, formed on or secured to one of the levers, as 5, and provided with a series of holes Z) and a locking-pin 17. The holes is plate 16 are spaced a greater distance apart than the holes otally connected directly to the lever 5 and.

the turnbuckle 8 is provided with a hand wheel 18, whereby said turnbuckle may be rotated. As the ends of the sections 7 and 7 are oppositely threaded and the turnbuckle has right and left hand threads at its respective ends, the rotation of the turnbuckle will effect a lengthening or shortening of the connection between the levers. Ifnow the lever 5be locked as against any movement, a rotation of the turnbuckle will effect a shifting of the lever 4, and thereby a raising or lowering, as the case may be, of one end of th upper roll.

I claim herein as my invention 1; In a rolling mill the combination of mechanism for simultaneously raising or lowering both ends of one of the rolls, a lock for holding a portion of the mechanism stationary, and means for shifting another portion of the adjusting mechanism and thereby raise or lower one end ofsaid roll, substantially as set forth.

2. In a rollingmill, the combination of screws for adjusting one of the. rolls, arms for shifting said screws, means for locking one of said arms, and means for shifting the other arm toward and from-the first arm,'substantially as set forth.

3.' In a rolling-.mill the combination of screws, arms for rotating said screws, a con- I SIGMUND v. HUBER.
